Sera Discus Granules Ingredients Analysis

The primary ingredient is fish meal. Fish meal is comprised of the leftovers (scales, skin, bones, internal organs) deemed unsuitable for human consumption. We have no way of measuring the quality of the meal being used. The source Sera uses for fish meal is unknown. As a result, the quality, subsequent nutritional value, and protein content, are questionable.

Mussel Meal, Krill Meal, and Shrimp Meal are additional preferred ingredients. Mussel Meal is a dried product manufactured from the edible meat of mussels (does not include the shell). It is high in proteins and calcium. Krill meal is a natural source of Astaxanthin, a red color enhancing carotenoid. As a general statement, shrimp meal is a lower quality than is fish meal.

Spirulina is sometimes called "The Most Nutritious Food on the Planet". Rich in raw protein and seven major vitamins: A1, B1, B2, B6, B12 (one of the best natural sources for B12, although the bioavailability of its B12 is in dispute by many researchers), C and E. It naturally contains beta-carotene, color enhancing pigments, and a whole range of minerals. In addition, Spirulina has 62% amino acid content and contains all essential fatty acids and eight amino acids required for complete nutrition. It is easily digested due to the fact that Spirulina cells do not have cellulose walls. Spirulina is only available in a dry form, so regardless of how it is listed on the ingredient label (spirulina meal, dried spirulina, or spirulina), it's ordering in the ingredient list should be accurate.

Four of the first five ingredients are preferred protein sources. Despite concerns with the quality of the fish meal used as the primary ingredient, there is ample confidence in the preferred protein content of this food.

It is not known if this food contains Ethoxyquin. Absent a manufacturer’s statement that it does not, we must assume it does. While synthetic vitamin K is not listed in the ingredient list, it can be assumed to be included under the label “Vitamins”. This food certainly contains artificial colors, one of which is Ponceau 4R, a known carcinogen banned from human consumption in many countries, including the United States.

Oscarfish.Com Rating: 2 Star

Based solely upon the preferred protein content of this food it would be worthy of a 3 or even 4 star rating. There simply is not sufficient confidence in the quality of the meals used in this food, combined with probable use of Ethoxyquin, synthetic vitamin K, and known use of artificial colors with known health risks, to justify a rating any higher. Ponceau 4R is an egregious enough ingredient, by itself, to prevent rating this above a 2 star food.

Understanding Oscarfish.Com Ratings:

This review is an attempt to analyze the ingredients, rating them from 1 (worst) to 6 (best) in an effort to judge quality based upon three simple criteria.

  1. Absence of toxic, potentially toxic, and controversial ingredients
  2. Aquatic Animal protein and Preferred Plant Proteins as the primary protein sources
  3. A fully nutritious food to include necessary vitamins and minerals with natural sources of vitamins and minerals being preferred.

These basic concepts apply:

  • Any food that utilizes Ethoxyquin, BHA, or BHT as preservatives, cannot rate higher than a 4 star food.
  • Use of artificial colors prevents rating higher than a 4 star food.
  • Any food that utilizes Menadione Sodium Bisulfite (Synthetic Vitamin K, aka K3) cannot rate higher than a 5 star food.
  • Inclusion of the “Whole Fish”, or “Whole Krill” (in meal form or not) is preferred over fish meal or krill meal.
  • In order to achieve a 5 or 6 star rating, the quality of the meal must be known.
  • In order to achieve a 6 star rating, the “Whole Fish’ (or whole animal) must be used, either in meal form or in sufficient quantities outside of meal form.
  • Inclusion of sufficient quantities of preferred plant proteins is a bonus with sufficient Spirulina content being a significant bonus.
  • Use of prebiotics or probiotics is a bonus

Yep... confirmed. Ethoxyquin remains an allowed feed additive in the EU, except for Dogs.

That would have to be a recent change. My understanding it is banned for human consumption but still allowed in fish feed.
Currently approved fish feed additive in EU with an upper limit of 150 mg/kg alone or in combination with butylated hydroxytoluene (BHT) and butylated hydroxianisole (BHA) as per EC 1831/2003.

The European Union has banned the use of ethoxyquin. They can't use it in the fish food. Sera is manufactured in Germany.

I loved your review and joined so I can read a lot more! Thank you!
